Pragmatic Topic Map Streaming by Jan Schreiber raises some interesting questions about how to construct a data stream for a topic map.
I particularly like the idea of creating mini-topic maps as it were. See his post for the details.
He did not touch on was how topic map stream software would recognize subjects. A topic map stream creator with a configurable subject recognition would be really useful. Most of us could use the “topic maps subjects” recognition filter while others, interested in dull subjects like the World Cup (just teasing) could have a subject filter for it. Some of us could have both, feeding different topic maps.
